Abstract

A circuit having a sensing circuit and at least one of a first node (VSSA) and a second node (VDDA) is described. The sensing circuit includes a pair of a first type transistors (N5,N6) and a pair of a second type transistors (P1,P2). Each transistor of the pair of the first type transistors (N5,N6) is coupled in series with a transistor of the pair of the second type transistors (P1,P2). The first node (VSSA) has a first voltage and is coupled to each bulk of each transistor of the pair of the first type transistors (N5,N6). The second node (VDDA) has a second voltage and is coupled to each bulk of each transistor of the pair of the second type transistors (P1,P2). During sensing, the first and second voltages are changed to reduce the threshold voltages of the pairs of first (N5,N6) and second (P1,P2) types of transistors, thereby increasing sensing speed.
